Wood-sawing machine



UNITED STATES PATENT OFFICE.

CHARLES V. BARKER, OF CHICAGO, ILLILTOIS.

WOOD-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 552,505, dated January '7, 1896.

' cation.

My invention relates to certain improvements in wood-sawing machines, its object being to simplify and cheapen the construction and adapt them to use with an ordinary horse-power; also to adapt them to a great range of movement without changing the position of the horse-power and to either saw in a vertical or horizontal direction.

My invention is fully described and eX- plained in this specification and shown in the accompanying drawings, in which Figure 1 is a top plan of my preferred construction. Fig. 2 is a side elevation looking in the direction of the arrow 2, Fig. 1. Fig. 3

is a broken detail side elevation showing certain parts of the mechanism on a larger scale and looking in the direction indicated by the arrow 3, Fig. 1. Fig. 4 is a section in line 4 4c, Fig. 1, and looking in the direction of the arrow 4. Fig. 5 is a section in line 5 5, Fig. 3, looking in the direction of the arrow 5; and Fig. 6 is a vertical section in line 6 6, Fig. 1, looking in the direction of the arrow 6.

Referring to the drawings, A is a horsepower made up of a frame of ordinary construction and provided with. a pair of runners a, so that it may be drawn along in moving it from place to place. A sweep A is rigidly fastened to one of the arms I) of the masterwheel B, which turns upon a shaft Z), journaled in suitable bearings 12'' b An arm 19 extends from the bearing 12 and forms a second bearing 12 in which is journaled a shaft 0, upon which is fastened a bull-pinion G. Suitable braces a extend from the frame and hold the arm 13 securely in place. The lower end of the shaft 0 is supported in astep c, and

carries near its lower end a beam D, provided necessary tilting motion in raising or lowering the saw-frame. The pitman is guided by means of a bolt 6 running between two parallel rods 6 e suitably supported upon the beam D The saw-blade F is carried by means of an arm f bolted to it, which is hinged at f to a second arm f and this arm is carried by means of a bolt f which passes through an eye in the lower end of the bolt 6 The sawblade is guided at one end by a suitable guide f and at the other end by means of a roller g, which is journaled on the hinge which connects the two levers f f, and this roller runs between two parallel bars G G, pivoted. at one end to the beam D at g, and having at their other end a slotted segment which can be held in any desired position by means of a thumbscrew or. A spring f tends to hold the sawblade against the log which it is sawing. The beam D is loosely pivoted to the arm D as will be seen at cl", so that it may be easily raised or lowered, or, if necessary, it may be turned so as to saw in a horizontal direction. When this is done the pitman is unbolted at one end and the bolt passed through a second hole at right angles to the one formerly occupied. 1

The machine may be drawn to any place where it is desirable to cut down a number of trees and saw them up into logs. When put in a certain position the saw has a great range of movement, as will be readily understood from the foregoing description. The swinging portion of the machine may be supported above the ground by means of a chain H.

I claim as new and desire to secure by Letters Patent- 1. The combination with the saw, F,ar1n f, carrying said saw, a second. arm, f hinged at one end to the arm, f, and provided with the roller, g, of the adjustable guide, G, adapted to guide said roller, pitman, E5, .rods, 6, adapted to guide the pitman, suitable connections between the pitman and the arm, f the beam, D supporting the saw and its connections, the beam, D and the swivel joint,

dflconnecting the beam, D ,with the beam,D whereby the saw maybe tilted at any angle and suitable means for giving a reciprocating motion to the saw; substantially as described.

2. The combination with the oscillating: frame, D of an adjustable guide, G, roller, 9,

the hinged arm, f spring, f pitman, E, connectmg devices between the arm, fiand pitman and the crank, E, provided with suitable means for its rotation; substantially as described.

3. In a wood-sawingunachine the combina- CHAR-LES V. BARKER.
